HINGE.

Specification of Letters Patent.

Patented Feb'. 11, 1913.

Application filed February 10, 1912. Serial No. 676,810.

To all whom, it may concern:

Be it known that I, ISAAC H. WATTERS, a citizen of the United States, residing at Galesburg, in the county of Knox and State of Illinois, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinges, and more especially to that class thereof which are ordinarily used to hang doors, and it has for one of its objects the provision of a hinge comprising a pair of leaves which are pivotally united by a pintle which is removable only when the door has been swung 0 en.

The invention has furthermore for its object the provision of locking means in connection with such pintle, these locking means being adapted to be removed entirely when deemed desirable, in which case the hinge would be converted into a loosepintle hinge.

Further objects of the invention will here inafter appear and be particularly defined in the claim.

The invention has been clearly illustrated in the accompanying drawings, in which similar characters denote similar parts, and in which Figure 1 is an outside view of a hinge shown in connection with a. door jamb and a door, the latter being closed. Fig. 2 is a horizontal section on line 2, 2 of Fi 1. Fig. 3 is a view similar to Fig. 1 the door being swung wide open. Fig. 4 represents a section on line 4, 4 of Fig. 3 and Fig.5 shows a perspective view the hinge disassembled to illustrate its component parts.

In the present instance I have illustrated my invention applied to a hinge for which United States Letters Patent were issued to me on Sept. 26, 1911 No. 1,004,317, to which reference may be had, the present device being particularly adapted for this style of hinge which can thus be converted from a loose pintle hinge into a fixed pintle device, so that the user is' enabled to change the operation of the hinge as he may desire without requiring a complete removal 'of the-hinge in its entirety. It should of course be understood that the present invention is applicable to the'ordinary style of butts, as well.

Referring to the drawings, 10 denotes a door jamb on which the door 11 is ivo't-' ally supported by a hinge comprising .a

leaf 12 provided with knuckles 13, 14 which are adapted to fit between knuckles 15, 16, respectively of the other hinge leaf 17 secured to the door. Both leaves are pivotally 1 above referred to. Now, since in some cases it may be desirable to convert this always free pintle hinge into one in which the pintle may be removed only when the door is in open condition, or in other words: as here shown when partly opened, means are provided whereby said pintle may be locked against removal at all other times. This means: that normally the pintle-lock can not be tampered with, and that consequently the pintle itself must remain in place.

Various means may be employed to accomplish this result, and I have shown in the present instance a pintle provided with an annular groove 20 adapted to be engaged by a lock screw 21 screwthreaded in the central knuckle 16 of the door-leaf, articu lar emphasis being laid upon this ocation of the screw relative to the hinge leaf 17 By referring to Fig. 2 it will be noted that the door 11 is closed, and that therefore the screw 21 is inaccessible by virtue of its outer head facing the door jamb, on account of the screw-axis being substantially parallel to the plane of the hinge leaf 17. When now the door is opened sufliciently to expose the head of the screw 20, and for instance indicated in dot and dash lines 11', or further as shown in full lines in Fig. 4, the screw may be removed and the pintle be then withdrawn. inasmuch as the pintle is rotatively free to move in the knuckles of both hinge leaves, there is no tendency for the pintle to creep upward even if the locking device should not be in evidence; but the latter will not only guard the pintle against accidental displacement, but will, furthermore, prevent a surreptitious removal. In other words, my improved hinge can be used in exactly the same manner and for the same purposes as the one previously patented to me, in which instance the screw 21 may either be withdrawn sufficiently to clear the shoulder formed by the groove 20, or in fact it may be removed entirely. On the other hand, by inserting the screw 21, the pintle becomes locked against removal so that therefore the functions of a fixed pintle hinge Will result, because no access can be had to the lock-screw unless the door has first been opened.

It is obvious that other means may be employed for locking the pintle in place instead of the screw named, and also that other changes can be made in the particular construction and organization of the com-- ponents of my improved hinge which constitutes a device adapted to be converted into the desired species without difliculty.
